Chin-Up Amplified: How to Do It & Muscles Worked

The chin-up is a bodyweight exercise that targets the latissimus dorsi (lats) and also works the biceps and forearms. It involves pulling your body up towards a bar with an underhand grip until your chin clears the bar.

How to do the chin-up amplified

  1. Step 1: Hang from a pull-up bar with your palms facing towards you and your hands shoulder-width apart.
  2. Step 2: Engage your core and pull your body up towards the bar, leading with your chest. Maintain amplified form throughout.
  3. Step 3: Continue pulling until your chin is above the bar.
  4. Step 4: Pause for a moment at the top, then slowly lower your body back down to the starting position.
  5. Step 5: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the chin-up amplified by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
